I think there is something nuanced here about my point that you aren't addressing. I have served Facebook ads through both a secondary vendor and through their interface. I can tell you with 100% certainty that my ads through the second party vendor overdeliver impressions based on the response rate of the ad. Unless my ad is complete garbage, I always get more impressions than I have paid for.

That's right, I get free impressions if my ad (not boosted post) does better.

How else I know this is that their video completion rate when calculated by impression is absolutely abysmal compared to other platforms. This is why they don't address VCR in their own interface. They want the ability to serve your ad however they see fit until there are results.

Also, I can ask Facebook to charge me only for plays, and you even alluded to the fact that you can pay for engagement as well. This backs up my point that Facebook will serve your ad as many times as it wants until it finds the right user-ad fit.

That being the case, I go back to what I already said. Yes, impressions are very important here, but they are not exactly what you are paying for. You are paying for user reach and engagement.

"Your ads will be deployed evenly over time, and you'll never be charged over your budget"

But your ads are usually served more than you ordered. Unlike other platforms, where I only get exactly as many impressions as I pay for.

In a way it is similar to Adwords Quality Score for CPC.

I think we're arguing semantics here. For context I also have bought FB natively and through a DSP for about 8 years. The phenomenon that you're referencing is what I was talking about with earned/organic impressions versus paid impressions. I assume you're buying fixed cpm on your secondary vendor? Again what is happening is people are sharing the ad or tagging people in the comment section. Those would be earned impressions and would increase your reach but that doesn't mean FB doesn't charge based on CPM. If I'm buying a magazine ad and someone showed that magazine ad to their friend that doesn't mean the magazine wouldn't still sell that ad slot on a CPM basis. I understand why it would seem they would charge on a different basis than CPM at first glance but I assure you that isn't the case. As for engagement and video views completion that's all well and good but that's an optimization option rather than a charging basis. By all means my job would be much simpler though if Facebook only charged me on a conversion basis though haha.

I suspect we're at an impasse but you really should reconsider your position and look at the nuance between earned/organic impressions you get from an ad and paid impressions. As an aside one thing we do agree on is the abysmal video completion rate.

I appreciate the conversation and will take another look into whether or not my raw impressions for my ads are getting mixed in with organic impression numbers.

Appreciate the conversation as well, and if you find that I'm wrong please do tell me! Always open to learning.
